Application March 17, 1936, Serial No. 69,258 Renewed May 21, 1938 1Claim.

Ribbon is usually prepared for sale and consumption by forming it into ahelically wound mass, usually upon a core the latter if present beingeither with or without a ange or flanges which flank the ribbon mass.(Whereas the invention has been devised with respect particularly totextile ribbons, by the term ribbon as herein used I mean to include anystrip of sheet material, whether textile or not.) Upon forming the woundbody it is usually necessary to secure the free end of the ribbon insome way so that the windings may be retained during subsequent handlingsubstantially in the same degree of compactness in which they wereinitially developed; and, where the ribbon is dispensed by cutting orotherwise detaching therefrom successive lengths which may vary inextent, as is usually the case, whatever securing expedient is used musttake into account that usually the actual point of securing will notremain during the life of the pack always in the same radial plane. Theconventional securing means, at once inexpensive and adapted to beapplied in any radial plane of the Wound body thus to hold the ribbonclear to its free end and in compact wound form, is a common toilet pinwhich is pushed through the free end of the ribbon into the wound mass.But this forms perforations in the ribbon and so spoils each convolutionpenetrated, and the damage thus done may be more or less according tothe number of times the pin is removed and re-entered at dierent points.

According to this invention, whereby the pinning is avoided withoutincrease in the cost of production, given a body including a helicallywound mass of ribbon, there is combined therewith an endless elasticband which constrictively embraces said body in crossing relation to theribbon windings and exists throughout its own extent exterior of saidmass, said band bearing against the periphery of the mass and said bodyhaving means to oppose dislodgment of the band therefrom in a directiontransverse of the axis of the windings. If, as is usually the case, saidbody includes a core for the windings said core will usually be providedwith said means, and if the core has a flange or flanges flanking themass said means may take the form of notches in such flange or anges inwhich the band is received. With such core present and said meansprovided on the core the mass may be rotative relatively to the core inwhich case the ribbon may be withdrawn without detaching the band fromthe core and the band may be made to hold the ribbon clear to its freeend.

(Cl. 20G-53) In the drawing,

Fig. 1 is a side elevation of one form of the improved ribbon pack;

Fig. 2 is a diametric section thereof in the plane of the notches; and

Fig. 3 is a section on line 3 3, Fig. 2.

The said body here includes the helical windings of ribbon I and aninterwound strip 2, as of paper, formed on a cylindrical shell 3 ofstiff sheet material, as cardboard, which forms with the windings what Iterm the wound mass, and a core on which such mass is free to rotate,the same comprising a wooden barrel 4 which freely penetrates the boreof such mass (specifically, of the shell) and two heads 5 nailed at 6 tothe ends of the barrel and affording anges which ilank said mass, thebarrel being of greater axial extent than said mass so that thereby, andbecause the bore of said mass is loose on the barrel, said mass mayfreely rotate on the core.

'l is the endless elastic band, here a plain rubber band, the sameconstrictively embracing said body in crossing relation to the ribbonwindings and existing throughout its own extent exterior of said massand bearing against the periphery of said mass, as at 8.

The said means to oppose dislodgment of the band from said body in adirection transverse of the axis of the windings is here formed byperipheral notches 9 and Il] in the flanges of the core, the notches 9being coincident with that radius of the body in which the band bearsagainst the periphery of the wound mass.

The construction is such that the band holds the wound mass in woundstate and is itself held against dislodgment from said body. To withdrawany desired length of the ribbon the band may be removed, or, accordingto the example shown and described in which said body includes, with thewound mass, a core on which said mass is revoluble, the ribbon may bewithdrawn with one hand, thus rotating the mass, while the core is heldagainst rotation by the other hand. In such case it is always possible,upon cutting off a piece of the ribbon, to have it held clear to the endof the remaining windings. The drawing shows that in the operation ofwithdrawing the ribbon the core may be held against rotation by thethumb and middle nger of one hand while the forefinger of such hand isused to hold the band out of the notches 9.

Having thus fully described my invention what I claim is:

The combination, with a helically wound mass of ribbon having an axialbore and a core to be 55 posed notches exposing laterally the windingsof said mass for an extent greater than one-half of its radial thicknessand in a radius remote from that of said notches other peripheralsubstantially opposed notches extending short of the periphery of themass, and said band being received in the several notches.
